Accurate monitoring of free flap perfusion after complex reconstruction is critical for early recognition of flap compromise. Surgeons use a variety of subjective and objective measures to evaluate flap perfusion postoperatively. However, these measures have some limitations. We have developed a wireless, biodegradable, and flexible sensor that can be applied to real-time postoperative free flap monitoring. Here we assess the biocompatibility and function of our novel sensor.

Wireless pH monitoring measures esophageal acid exposure time (AET) for up to 96 hrs. We evaluated competing methods of analysis of wireless pH data.
There is a growing trend across health care to perform increasingly complex procedures in less acute settings. This shift has been fueled, in part, by enhanced recovery protocols, which have shorte...
Change of respiratory rate (RespR) is the most powerful predictor of clinical deterioration. Brady- (RespR ≤ 8) and tachypnea (RespR ≥ 31) are associated with serious adverse events. Simul...
The radial forearm free flap (RFFF) is a commonly used free flap for tongue cancer. Postoperative changes in the volume of free flap are known to influence the functional restoration of the resected t...
To compare intraoperative, postoperative, functional, and oncologic outcomes of the submental island pedicled flap (SIPF) to the radial forearm free flap (RFFF).
This is a pilot study is to test a wireless, skin-sensor device against current technology in the CCU to monitor vitals
A simple device that objectively assesses flap perfusion - either as a stand-alone tool or an adjunct to the current monitoring method - would be a tremendous improvement in detection of e...
The purpose of this study is to evaluate the performance of the EchoMark and EchoSure as an ultrasound-based method of monitoring the viability of free flaps and patency of at-risk vessels...
This study evaluates donor site outcomes in patients receiving radial forearm free flap reconstruction versus ulnar forearm free flap reconstruction. Patients who meet criteria for forearm...
To estimate the clinical effectiveness of wireless physiologic monitoring of women in the first 24 hours after cesarean delivery at Mbarara Regional Referral Hospital
Small-scale tests of methods and procedures to be used on a larger scale if the pilot study demonstrates that these methods and procedures can work.
Endonucleases that remove 5' DNA sequences from a DNA structure called a DNA flap. The DNA flap structure occurs in double-stranded DNA containing a single-stranded break where the 5' portion of the downstream strand is too long and overlaps the 3' end of the upstream strand. Flap endonucleases cleave the downstream strand of the overlap flap structure precisely after the first base-paired nucleotide, creating a ligatable nick.
Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.
Techniques using energy such as radio frequency, infrared light, laser light, visible light, or acoustic energy to transfer information without the use of wires, over both short and long distances.
